IFFB% – This stands for infield fly ball percentage, which is the percentage of fly balls a player hits that end up as infield pop ups. Lazy flies to the infield are about as easy to field as they come, so they are considered essentially automatic outs. Because of that, it would be fair to say that a player who hits a lot of infield flies is not likely to have a very good BABIP. However, even the player with the worse IFFB% last year was at just 17.3%, so hitting a lot of automatic outs isn’t going to make a huge difference, but definitely a noticeable one. Batters who avoided these easy outs last year (better-than-league average IFFB%) had a better BABIP (.312) than their counterparts who did not (.298).
In the major leagues, .300 always has been regarded as a special number. Like a 20-point-a-game scorer in basketball or a 1,000-yards-a-season rusher in football, it is a benchmark for excellence. A .300 season will get you a pay raise, which is why so many players through the years have asked off on the last day of a season. They wanted to preserve their precious .300.

Some fantasy scoring systems count on-base percentage in lieu of batting average. But regardless of a league's offensive-rate stat of choice, OBP tends to correlate with runs scored. And because Major League front offices value OBP highly, low-average hitters often receive their ample share of playing time -- and, thus, opportunities to accumulate fantasy counting stats -- as long as they walk enough to post satisfactory OBPs.
Well, if you go to Fangraphs.com, go to the player stats page and you click on "Advanced" (which is code for sabermetrics), you’ll see that there are several statistical categories after each player, but they are sorted according to wOBA, by default. So, perhaps wOBA is to sabermetrics what batting average once was to statisticians of the 1950s and 60s. Probably the most important measure of a player’s offensive value.

The Hitters Power Drive device is very portable. The built in handle makes it easy to carry and transport. The device can be used on a floor, flat ground, any outdoor surface or indoor practice surface. Hitters can practice from the hitting training aid on their own with or without hitting baseballs from their hitting power initiation position. Without having to hit baseballs to practice and receive feedback it allows use in their yard, inside their home, basement and garage. With the unit being very portable measuring 14’inches in circumference” and weighing approximately 19 pounds they can transport from their home to the yard, gym, training rooms / facilities or field.
If you take a batting average and multiply it by 100 (or slide the decimal point over two spots to the right), it will give you a raw percentage of how often a player gets a hit. So using Mike Trout’s batting average as an example, he accumulated 172 hits in 602 at bats last year for a batting average of .287 (172/602). Multiplying .287 by 100 gives you 28.7 which tells you that in 2014, Mike Trout averaged a hit in 28.7% of his at bats.
Lanky build and weak muscles are not going to cut it if you dream of hitting home runs in a baseball game. You need to build your upper body and muscles, so the most basic thing to do is regularly bring these muscles into action, exercise and toughen them up. Try to do such exercises on a daily basis which involve your entire upper body. This will give you the requisite strength to hit a baseball farther.

A major league pitcher can throw a baseball up to 95 miles per hour -- some can move it even faster. At this speed, it takes about four tenths of a second for the ball to travel the 60 feet, 6 inches from the pitcher's mound to home plate, where the batter, with muscles as tense as coiled springs, like a predatory animal about to pounce, waits for the precise moment to swing at the ball. Baseball is a game played at the edge of biological time, just within the limits of a human's ability to react.
Why should we use OBP? What advantage does it possess over batting average? The primary benefit of OBP is that it measures a player's performance with regards to avoiding outs. Baseball does not have a clock like so many other sports. Rather, baseball teams operate under the constraint of 27 outs. Once a team has used all 27 of its outs, then the game is over.
At the point of contact, we see a culmination of every drill worked on for power thus far. First, from the interlocking throws drill, we have a good palm up, palm down path at the point of contact. From the half and full turn drills, we see she has great hip rotation to the ball, from the paint stick and don’t squish the bug drills, she has excellent weight transfer to the launch point, so great that her back foot has come off the ground and moved forward. She is generating power from the lower half and harnessing it with her bat path. The crossover drill is a great drill to finish off the set of previous drills designed to generate power for softball.
The last notable disadvantage of OBP is that it is not park or league adjusted. It is easier for players to post a higher OBP in parks such as Fenway Park or Coors Field than the Oakland Coliseum or Petco Park. Likewise, OBP has fluctuated throughout time. Carl Yastrzemski led the American League with an OBP of .395 in 1965. However, in 2001, Jason Giambi put up the highest mark at .477. There are ways to adjust numbers for park and league context, but we'll save that topic for a later date.
To stay connected to the body's rotational energy, it is very important that the first movement of the hands is not directed toward the pitcher - or inline with the incoming pitch. The batter should keep his hands back and allow the rotation of the body against the lead arm to accelerate the hands. The first movement of the hands will then be propelled more perpendicular to the flight of the incoming ball. This will induce the greatest amount of angular displacement to the bat and propel the hands into the most productive path.
Here are our nine candidates for best primary offensive stat -- and please note that every offensive stat here is very important, we're just trying to pick which is the top dog. Also note, categories such as doubles, triples and stolen bases are clearly important but couldn't be rationally argued as the most important stat. Thus, they were left out. - Matt Snyder
By the time the ball has traveled a dozen feet from the pitcher's mound, the batter has a good visual fix on it. In a thought process much too quick for deliberation, he has decided whether the pitch is a fastball, curveball, slider, knuckleball, screwball, or whatever -- yet a good deal of data has gone into this instantaneous and non-verbal decision.

You can make similar cases for mid-range average guys like Ben Zobrist and Jason Heyward who had averages in the .270 but on base percentages in the .350’s because they could draw walks.  I know, you could just add walks as a category but in doing so you would be penalizing players like Jones along with some of the players from the BA leaders above like Lorenzo Cain, Ben Revere and Josh Harrison.  Now you’re still gonna have those high empty OBP guys just like you would empty BA guys; nothing you can do about that, no system is perfect.  The difference is the right players are being rewarded.  If your hits and walks are equal you are getting on base at an equal clip, right?  Getting on base helps your team, just ask Billy Beane. 
There is a very important Biomechanical Principle that pertains to the initiation of the baseball swing. The principle states: "A ballistic motion, once initiated, produces trajectories that can only be changed at its margins." This means, the forces applied to the bat during initiation produce trajectories that will set the tone for the entire swing. If the swing is not initiated correctly - little can be done to compensate for it.
On base percentage (OBP) or on base average (OBA) is an important component in a sabermetrics styled view of offensive productivity, but it is by no means the ultimate statistic to measure a hitter’s value. Unlike AVG and SLG, OBP does take walks into account, but it gives the same weight to a home run as it does to a single or a walk. Obviously, those are events in a baseball game that don’t have the same value in terms of producing runs. Billy Beane was quoted once as saying that OBA is three times as important as SLG. Well, is it? Not from a sabermetrics view point. Sabermetrics isn’t based on money at all. Bill James and the folks that blazed the trail for the development of sabermetrics certainly know that a home run has more value than a walk. It just so happens that players that had an ability to get on base were not paid as well as some of those who racked up RBIs. Obviously, the players who do it all get paid the most.
Don't swing down on the ball. The backspin you gain from doing so does not outweigh the exit velocity loss that occurs as a result. The best way to get distance is to swing up through the ball. If you slightly undercut the ball that way, you get backspin while achieving a better launch angle and maintaining as much exit velocity as possible. Advanced analytics show that the most effective way to hit home runs is to swing with an attack angle that's slightly less than the ideal launch angle. The following article explains this in more depth.
Traditionally, players with the best on-base percentages bat as leadoff hitter, unless they are power hitters, who traditionally bat slightly lower in the batting order. The league average for on-base percentage in Major League Baseball has varied considerably over time; at its peak in the late 1990s, it was around .340, whereas it was typically .300 during the dead-ball era. On-base percentage can also vary quite considerably from player to player. The record for the highest career OBP by a hitter, based on over 3000 plate appearances, is .482 by Ted Williams. The lowest is by Bill Bergen, who had an OBP of .194.
Great article! Your explanation of what it means to “relax” is definitely something all hitters struggle with, including myself. I’ve always been a “power-hitter”, but I didn’t really start hitting HRs consitently until I started putting backspin on the ball. For me at least, focusing on my swing and trying to have a backspin-promoting cut helped me RELAX and take the focus off of trying to kill the ball. I would grip the bat way too tight and pull everything, which was really frustrating. Another thing that helped me keep my hands relaxed was I started using that Pro-Hitter thumb ring that I saw pro’s like A-Gon and J Hamilton using… Again, great article! Thanks for providing more insight on something that all of us wish we could do at every at-bat haha! One can only dream…
All joking aside, "hitting for contact" is a much better way to describe the "hit" tool. When scouts talk about players with the hit tool they aren't saying, "this is a guy who could really get a few ground balls through the infield and survive off an inflated BABIP", they are saying something far more basic and important: "this guy can hit a baseball." If a player makes it to the major leagues as a position player they probably have some kind of knack for hitting baseballs, but some players are definitely better than others. More importantly, for the purposes of this series, there is one player who is the worst. The first name that probably comes to mind for many readers is Adam Dunn. However, there is a new king when it comes to the whiff, and that man is Chris Carter of the Astros.
